IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 35,668, dated June 24,1862.

To all whom it may concern:

Be it known that I, A. B. CASS, of Muscatine, in the county of Muscatineand State of Iowa, have invented a new and Improved Corn Plow orCultivator; and I do hereby delare that the following is a full, clear,and exact description of the same, reference beinghad to theaccompanyingdrawings, making a part of this specification, in which- Figure 1 is asectional side view of my invention, taken in the line m as, Fig. 2.Fig. 2 is a plan or top view of the same. Fig. 3 is a front view of thesame.

Similar letters of reference indicate coriesponding parts in theseveralfigures.

The object of this invention is to obtain a orn plow or cultivator whichwill admit of having its plows shifted or moved by the driver on hisseat, so that the plows may be adjusted with the greatest facility toconform to the sinuosity of the rows, and at the same time admit ofbeing readily raised above the surface of the ground when it is desiredto have the implement inoperative, as when being drawn from place toplace, turning at the ends of rows, &c.

To enable those skilled in the art to fully understand and constructmyinvention, I will proceed to describe it.

A represents a rectangular frame, which is shovel-shares, O 0, attachedto its front part. These shovel-shares have their standards a fitted onpivots a a in the frame A, and they are connected at their upper ends bya crossbar, D, the central part of which is rounded, as shown at b, andhas the front end of a lever, E, connected to it. This lever E has ajoint, 0, at its center, and its back end is attached by a pivot, d, toa lever, F, the lower end of which is fitted within a curved guid'e, Gr,attached to the back end of the frame A. The lever F passes up throughthe drivers seat H, which rests on a slotted curve or segmental support,I, the seat having pendent guides c 0 attached, which pass through theslot of the support, the latter being attached to inclined bars ff onthe frame A. The pendent guides e e are connected by a crossbar, 6*,through which the lever E passes.

' J J represent two shovel-shares, the standards g of which are fittedloosely on a cross- I bar, K, placed transeversely in the frame A, andhaving tenons at its ends which are allowed to turn in the frame. Theupper ends ofthe standards 9 gare connected by a crossbar, L, which isattached to the lever E, as shown at h.

The operation is as follows: The driver sits upon the seat H, and as themachine is drawn alougtheshovel-shares O O smooth or prepare the way forthe wheels 13 B, this being the only function they perform, and toeffect such result they are placed directly in front of or in line withthe wheels. The shovel-shares J J plow the corn, one being at each sideof the row, and the driver by shifting the seat H along on the segmentalsupport I moves the standards g of said shares on the cross-bar K eitherto the right or left, as the sinuosity of the row may require,therebycausing the corn to be plowed in a perfect manner. The driver by movingthe upper part of thelever F backward by pressing his back against itactuates the lever E and draws back the upper ends of theshare-standards, so that the shares will be elevated above the surfaceof the ground and the implement thereby rendered inoperative. Thisposition of the shares is indicated in red outline in Fig. 1, and thelateral movement of the shares J J is also indicated in red in the samefigure. By having the lever E jointed, as shown, the cuvilinear movementof the share-standards is compensated for. The lever E is connected tothe cross-bar D of the sharestandards in such a manner as to admit ofthe lateral movement referred to.

Thus by this very simple arrangement an efficient corn plow orcultivator is obtained, and one that may be readily operated and beunder the complete control of the driver.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The pivoted share standards a a and sliding share standards 9 9,connected to the jointed adjustable lever E, in combination with theseat H, and lever F, connected to a lever,

E, and the seat-support I, all arranged as and v for the purposespecified.
